Tikamanena za kukhazikitsa mlengalenga wodzithandizira, chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pakutumizirana mtunda wautali ndikuyika zingwe za fiber optic munsanja zamphamvu kwambiri.
Zomangamanga zamakono zomwe zili ndi mphamvu zambiri zimayika mtundu wokongola kwambiri woyikirapo chifukwa amachepetsa ndalama zomwe zimafunikira kuti apange maulalo atsopano a fiber optic, omwe amangidwa kale.Koma mizere ya nsanja zokhala ndi mphamvu yayikulu nthawi zambiri imakhala ndi zovuta zazikulu, zomwe zimawonedwa nthawi zambiri pazida zomwe zimagwira ma voltages apamwamba kwambiri: kutsata ndi kutulutsa kwa corona.
Kodi kutsatira zotsatira zake ndi chiyani?
Zomwe zimadziwikanso kuti ma banding owuma kapena arborescence yamagetsi, kutsata kumatanthawuza kuwonongedwa kwa dielectric kwa insulating material, njira yosasinthika yochokera kuzinthu zamagetsi zomwe zimatuluka mkati kapena pamwamba pa dielectric material ikafika nthawi yayitali. - mphamvu yamagetsi yamagetsi.
Kutuluka kwa Corona
Chiwopsezo china chomwe zingwe zodzithandizira zokha zimathamanga zikayikidwa munsanja zamphamvu kwambiri ndi corona effect, yomwe imadziwikanso kuti corona discharge, yomwe imatanthauzidwa ngati ionization ya gasi yomwe imazungulira kondakitala.Pakuyika chingwe cha fiber optic, mpweya ndi mpweya womwewo, womwe umazungulira mzere wotumizira.
Mphamvu ya corona imapezeka pazida zonse ndi kukhazikitsa komwe kumagwira ntchito kapena kuyendetsa magetsi.M'moyo wathu watsiku ndi tsiku, izi sizimamveka ndipo sizimatikhudza kwambiri chifukwa cha ma voltages ndi mphamvu zamagetsi zomwe timagwiritsa ntchito nthawi zambiri.Komabe, munsanja zamphamvu kwambiri, ma voltages omwe amayendera mizere yawo amakhala okwera kwambiri (kuchokera pa 66 kV mpaka 115 kV), zomwe zimapangitsa kuti mphamvu ya corona yopangidwa ndi ma conductor awa ikhale yotakata kwambiri.
Zingwe zikawonekera kunja, zingwe zimakhudzidwa ndi zinthu ziwiri zofunika: chinyezi cha mpweya ndi index yoyipa ya chilengedwe.Ndi chinyezi chochulukirapo, madzi ambiri amathira pamwamba pa chingwe;ndi kuipitsidwa kwakukulu kwa chilengedwe, tinthu tambiri (fumbi, zitsulo zolemera, mchere) zidzatsekeredwa m'madontho amadzi omwe amapanga.
Madonthowa okhala ndi zonyansa amakhala ochititsa chidwi, pamene mphamvu ya corona ya mzere wothamanga kwambiri ifika madontho awiri omwe ali pafupi kwambiri ndi wina ndi mzake, arc yamagetsi imapangidwa, kutulutsa kutentha pakati pawo ndi kuwononga jekete lachitsulo.
Chitetezo cha chingwe ndi zida zotsutsana ndi kutsatira
Ndikofunikira kwambiri kugwiritsa ntchito zinthu zotsutsana ndi kutsatira pakuyalaChingwe cha ADSS fiber opticspafupi ndi zida ndi zida zomwe zimagwiritsa ntchito mphamvu zamagetsi za 12 kV mpaka 25 kV.Izi zitha kukana bwino kutulutsa kwamagetsi, kuchepetsa zotsatira za ionization, kutentha, ndi kuwonongeka kwa zingwe.
Zida zotsutsana ndi kutsatira zidagawidwa m'magulu awiri akulu, zida zamagulu A ndi zida zamagulu B:
Zida zamagulu A
Zida za Class A ndizomwe zimakwaniritsa njira zokana kutengera mphamvu yamagetsi yomwe imagwiritsidwa ntchito komanso kuipitsidwa komwe kumayesedwa pansi pa muyezo wa IEEE P1222 2011, izi zimawonedwa ngati "zokhazikika" pamsika.
Zida zamagulu B
Zida za Gulu B ndizomwe sizili pansi pa muyezo, izi sizikutanthauza kuti zidazi siziteteza ku zotsatira zotsatiridwa, koma zimayendetsedwa ndi magawo kapena mikhalidwe yapadera yofotokozedwa ndi wopanga, kaya ndi ntchito zapadera. kapena zofunikira kwambiri, kalasi iyi ikhoza kufotokozedwa ngati "mwambo".
Malangizo aChingwe cha ADSSkukhazikitsa mu nsanja zamphamvu kwambiri
Kukonzekera n’kofunika kwambiri.M'pofunika kuganizira za kuipitsidwa index ndi voteji unsembe pamene paokha kuthandizira CHIKWANGWANI optic chingwe aikidwa pa mtunda wautali, high-voltage nsanja.Malingana ngati tili mkati mwa magawo omwe amakhazikitsidwa ndi IEEE P1222-2011, tikhoza kugwiritsa ntchito zinthu za kalasi A, zomwe zimapezeka kwambiri pamsika;pazovuta kwambiri zachilengedwe kapena ma voltages apamwamba, ndikofunikira kugwiritsa ntchito zida zamagulu B.
Lumikizanani ndi wopanga chingwe chanu kuti mudziwe mtundu wazinthu zomwe zingagwiritsidwe ntchito kuteteza bwino kukhulupirika kwa chingwe pakuyika kwanu, kukwaniritsa zomwe chingwecho chidzawululidwe.
Tingakuthandizeni bwanji?
ZathuGL FIBER® mainjiniya ndi akatswiri ogulitsatikuyembekezera kukuthandizani kuti muyike, tilankhule nafe lero ndikuwona zingwe zathu zambiri za ADSS fiber optic zomwe zili ndi anti-tracking kapena jekete zokhazikika pano.
